HANDLE FOR CROSSCUTHSAWS.

SPECIFICATION forming part of Letters Patent No. 395,218, dated December25, 1888. Application filed August 25, 1888. Serial No. 283,741. (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, CHRISTOPHER EISEN- HARDT, a citizen of the UnitedStates, and a resident of Philadelphia, Pennsylvania, have inventedcertain Improvements in Handles for CrosscutSa\vs, of which thefollowing is a speeiiication.

The object of my invention is to provide a simple and inexpensive butsecure form of 1o clip whereby a crosscut-saw handle maybe secured tothe end of the blade ot the saw, and this object I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which- Figure l is a view, partly in section and partly in elevation,showing part ot' the end of the blade of a crosscut-saw, the handletherefor, and a clip constructed in accord ance with my invention. Fig.2 is a view, partly in elevation and partly in section, on the line l 2,Fig. l; and Figs. 3 and -l are views illustrzfiting nnnlitications ofthe invention. V

A represents part ot' the end of the blade of a crosscut-saw, and B thehandle to be secured thereto, this handle having at the lower end all'errule, I), to which is swiveled a ring', F, notched for thereception of the upper edge ot' the blade ol the saw, as usual.

, The lower end ol the handle l5 has a cylindrical bore, u, into whichis titted snugly a sleeve, l, preferably ot some tough wood,this sleeveresting at its lower end upon a tubular flange, d, forming part ol" thet'errule I) and entering the lower end of the bore u. Up through thistubular tlange and through the sleeve b passes the clip-rod G, the lowerend ot which is slotted for the reception of the blade oli' the saw, theupper end ot' the rod being threaded lor zulaptaton toa nut, II, whichis in the lorm olf an inverted conc, the conical portion beingprovidedwith sharpedged ribs or ieethf, as shown in Eig. 2.

The conical nut l-l bears upon the upper end of' the sleeve l), and,owing to its sharpedged ribs or projections, is prevented from turningindepemlently of said sleeve, which in turn lits so snugly in the bore aof the handle l that when the latter is turned the sleeve will be turnedwith it, thus rotating 5o the nut and causing' the rise or fall of theclip-rod G, dependingl 'upon the direction in which the handle isrotated.

In securing' the handle to the blade the rod is drawn up easily untilthe upper edge of 5 5 the saw seats itself in the notches of theswivel-ring, F, whereupon further rotation of thenut H will cause thesame to be drawn downward in the handle, and the conical face of the nutwill thus eXpand the upper por- 6o tion of the sleeve B forcibly againstthe sides of the bore a in the handle, so that the harder the pull uponthe blade the more intimate will be the frictional contact between thesleeve b and the handle and the less the liability of the handle to slipupon said sleeve when it is turned.

Although, as before remarked, I prefer in carrying outniy invention touse a wooden sleeve, Ab, a metal sleeve, b, split at the upper end, asshown, for instance, in Fig'. so that it can be expanded into the bore aot' the handle when acted upon by the conical nut H, maybe used in placeof the wooden sleeve, it' desired, or where there is a very snug tit of75 the sleeve in the bore ol the handle the conicalexpansion feature maybe omitted, the nut in this case havingon its under side teeth forengaging with the top ot.' the sleeve. (See Fig. 4.) 8O

l Iaving thus described my in vention, I claim and desire to secure byLetters Patent#- l. The combination of the bored handle, the sleevelitted snugly therein, the threaded clip-rod, and a nut adapted to saidrod and toothed for engagement with the upper p0rtion of th e sleeve,whereby said nut and sleeve are compelled to turn together, allsubstantially as specified.

2. The combination of the bored handle, the sleeve fitted snuglytherein, the threaded clip-rod, and the n ut engaging' with the upperend of the sleeve and having' a conical portion for expanding the sameagainst the sides ot' the bore when the nut is subjected 95 to strain,all substantially as specified,

3. The combination of the bored handle, In testimony Whereoflhave signedmy name the sleeve fitted snugly in said bore, the to this speoiioationin the presence of two Subthreaded clip-rod, and the nut adapted theretoseribing Witnesses.

and having L conical portion with Shzup- CHRISTOPHER ElSENl-IARDT. 5edged I'ibs or teeth for engaging with the upfitnessesc per portion' ofthe sleeve, all substantially as EDWARD M. RILEY.
